Abstract: A method for operating an AC LED is disclosed. The method operates with an assumption that a linear relationship exists between the voltage and current of the AC LED operating at an active region. Hence, a first driving voltage and a second driving voltage are applied to the AC LED for respectively measuring a first driving current and a second driving current, and an interpolation is used for obtaining a third driving voltage. The third driving voltage is the predicted driving voltage for the AC LED. The method is capable of determining the actual driving voltage precisely and rapidly before the follow-up tests for other AC LEDs may proceed.
